FALL RIVER — A man was stabbed in the back early Sunday morning during a fight on Grant Street, police said.

The victim was treated at Charlton Memorial Hospital. His wound was not life-threatening, Fall River police Lt. Ronald Furtado said.

The victim, 29, told Officer Andre DeMello that two men — both described as Hispanic, thin, and about 5 feet, 6 inches to 5 feet, 8 inches tall — assaulted him while he, his wife and two children were leaving a party just before 3 a.m. on Sunday, Furtado said.

The assailants and the victim allegedly exchanged words as they passed each other, which led to the altercation. At one point, one of the assailants brandished a large knife and stabbed the victim in the lower left part of his back, Furtado said.

The victim went to the Charlton Memorial Hospital’s Emergency Room, which contacted police. The victim said he did not know in which direction the assailants fled, Furtado said.
